Total Blocks vs Wall Length
公式
## Retaining Wall Block Calculation **Blocks per Row = Wall Length (in) / Block Length** **Rows = Wall Height (in) / Block Height** **Total = Blocks per Row × Rows × 1.1 (waste)**
计算示例
20 ft long, 3 ft high wall with 12×4 in blocks.
- 01Blocks per row = 240/12 = 20
- 02Rows = 36/4 = 9
- 03Base total = 20 × 9 = 180
- 04With 10% waste = 198 blocks
常见问题
Do I need a permit for a retaining wall?
Walls over 4 feet typically require a building permit and may need engineering. Check your local codes.
